When your microfiber towels are not in use,you need a solution for keeping them.Plastic storage totes are an inexpensive solution - the lid will keep your towels from collecting dust in an area like a garage and will also minimize the amount of crawly insects that might find a new home buried in all that plush softness.Always be sure your microfiber is completely dry before storage. Mildew will form on towels in some climates if they are even slightly damp.
